Make this your JDBC driver
for MMBase
by editing
/usr/local/tomcat/webapps/mmbase-webapp/WEB-INF/config/modules/jdbc.xml.
Substitute the database name
(mmbase),
user (mmuser)
and password (mmpass)
with the database settings you'd like
MMBase to use.

Substitute the hostname (<hostname>)
and domain name (<domainname>)
with your own hostname and domain name,
and the database name (<mmbase>),
user (<mmuser>)
and password (<password>)
with the values you just entered in the JDBC driver configuration file.

If you are already using quite some
MySQL connections
(for example for authentication by and as a back-end to your mail daemons
and Apache servers),
the MySQL server
might run out of connections (its maximum number defaults to 100).
Then Tomcat
could simply refuse to start or give an error message
when initiating the
MySQL connection pool,
or your IMAP
or POP servers will have
problems authenticating their clients.

You can increase the maximum number of connections
to MySQL
by adding to the configuration file
/etc/my.cnf:
